the difference between purslane and potulaca

You can plant purslane safely — you just need to put it in the right place, because your wife isn’t wrong: purslane spreads fast, and if you plant it right next to your shrubs, it will creep into them. Where to plant purslane? Short answer: Plant purslane in open, sunny areas with clear borders, not directly inside or right against existing bushes. Use spots where you can easily control its spread. 🌿 Where purslane won’t invade your bushes Along garden edges — driveways, walkways, patio borders. It stays low and you can trim it easily. In containers or raised beds — zero risk of invasion. In a dedicated sunny patch — purslane loves heat and poor soil, so even a dry corner works. Between widely spaced plants — only if you’re willing to pull runners that wander too far. 🌱 Where you should NOT plant purslane Right under shrubs or bushes It will spread into the root zone and become annoying to remove. Next to slow‑growing ornamentals Purslane grows faster and can outcompete them. Anywhere you don’t want a groundcover Purslane is a champion spreader. 🌼 How to keep purslane contained Mulch around your bushes — purslane hates thick mulch. Create a physical border — bricks, stones, edging. Harvest often — the more you pick, the less it spreads. Pull runners early — they come out easily. 👍 Best practical placement for you Since you already have bushes your wife is worried about, the safest choice is: A sunny, open spot away from the shrubs — or a container. Purslane thrives even in poor soil, so you don’t need a fancy setup. What’s the actual difference? 1. Botanical identity Purslane (Portulaca oleracea) Edible, widely used as a leafy vegetable.
